Tutorial 14 word document missing essential info on synchronization

[omd24]

I like these concise word documents explaining the main idea for each tutorial but IMHO the doc for the Tutorial 14 is missing a rather important note on synchronization problem when updating the TLAS resources. The code is working properly and it has a comment explaining the changes made to the endFrame() function but for people who are following the docs files code walkthroughs it might take a while to find out why their code is not working. Therefore mentioning the problem might be really helpful.
